Abstract
Disclosed is an automatic sample changer for sequentially operating on a plurality of samples housed in test tubes, circulated around a continuous track, and sequentially associated with a radiation counting device by way of an elevator mechanism. The continuous track is in modular form, and is designed, respectively, to accommodate fifty, one hundred, two hundred or three hundred samples. Rotating index wheels are employed to drive the samples around the track, with several index wheels being used for the longer tracks. The motors controlling the respective index wheels are reversible, and when more than one motor is employed, the motors may be operated in parallel. Also disclosed is a mechanism for loosely coupling the index wheels to their associated motors to facilitate repair and ensure accurate alignment with the plane of the continuous track. The inventive sample changer is also equipped with an electronic index display which may operate independently of the sample changer power supply, and a mechanism for indicting a low paper level in the print-out roll.
